Foaming agent composition for foam concrete in low-temperature environment and foam preparation method

The invention discloses a foaming agent composition for foam concrete in a low-temperature environment and a foam preparation method, the foaming agent composition comprises 10-20 parts by mass of a surfactant, 8-12 parts by mass of calcium chloride, 2-3 parts by mass of glycerin, 2-4 parts by mass of a temperature adjusting capsule and 60-70 parts by mass of water, and the temperature adjusting capsule accounts for 2-4% of the total mass of the foaming agent composition. The problems that traditional foam concrete is low in foaming efficiency and poor in foam stability in a low-temperature environment are solved. 本发明公开了一种用于低温环境下泡沫混凝土的发泡剂组合物及泡沫制备方法，包括：10～20质量份的表面活性剂、8～12质量份的氯化钙、2～3质量份的甘油、2～4质量份的调温胶囊和60～70质量份的水，所述调温胶囊占发泡剂组合物的总质量的2～4％。本发明解决了传统的泡沫混凝土在低温环境下发泡效率低和泡沫稳定性差的问题。
